Read itGames by AI model version, compared
A model version is the exact release that wrote the code, like Claude Opus 5.5 and GPT-6 Astra. Only 61 of the 588 games we list name one, because most creators name the family or the tool instead. The table shows every version that has its own page, along with the tools and engines it was paired with and its top-ranked game.

Questions
Which AI model version is named most?
Claude Opus 5.5, on 25 games. GPT-6 Astra follows with 10. Only 61 of the 588 games we list name an exact version.
Why do so few games name a model version?
Creators usually say which tool they used, such as Claude Code or Cursor, and the tool picks or switches models along the way. We only record a version when the creator states it.
Where do these numbers come from?
They come from the 588 games we list. Creators name the AI, the tools and the engine when they submit a game or in their jam entry, and we don't verify those claims. One game can name several, and the full dataset is free to download from our statistics page.
